To all whom may conccm:

Be it known that l, CLIFFORD A. l i oons, a citizen oil the United States, residing at Plankinton, in the county of Aurora and State of South Dakota, have invented an Automobile Powerdlalotor, of which the tollowing is a specification. p

This invention relates to an automobile power motor which is designed to transmit power from the-drive wheels of the automobile to miscellaneous machinery, Wherebythe same may be adapted for numerous uses when not upon the oad.

The invention is particularly adaptizd for use in rural districts wherein the drive .wheels when rotated by the'inotor of the vehicle may be properly held inposition to transmit power for operating corn. shellers, fanning mills and numcn ous other machinery.

l further objecu is to provide Ineans forholding the automobile in a proper positionfor actuation of the power motor.

Other-objects and advantages will be ap parent firom the following description, and it will be understood thatchanges in the specific structure shown mid described may '.be made within the scope of the claims withoiit departing invention.

In the drawings: Figure l, is a top plan View of the device, Fig. 2 is a side 'eleva-- tion thereof, Fig. 6 is a perspective View; of a portion of the axle clamp on an enlargedscale, Fig. 4: is a longitudinal sec-.- tional view of a portion of the device.

Referring to the drawings in which simi;- lar characters refer to like parts throughout the several vie s, I have shown a platform having a horizontal surface 10 andfrom the spirit of the,

suitably inclined approaches ll at each end thereof, said platform constituting the framework the machine. A pair of drums 12 of proper size and having rubber coveredsnrfaces 12 are rotatahly journalcd. in. automatically oiled bearings 13 supported upon the frameworlrt and said drums are spaced a proper distance apart to allow the drive wheels 0t various makes of automobiles to have correct bearing thereon, so as to'properly engage-both. of the drums without engaging the horizontal surlzn'ge 10 of the platii'n'n'i. it will also be noted in the drawings that the drums are rotatable within the pla'tt'orni and project a proper distance above the horizontal survided with-a series of opening .face 10 to permit such engagement of the drive wheels. The shafts 14 to which the drums are rigidly" secured are projected through one side'ot the platform and have (39 gear Wheels 15 keyed thereon. A shaft 16 is rotatably carried by the frame stroo tu're intermediately between the gear;

wheels 15,1and the bearing bracket 17 is seemed, to one side of the platform to form a properbearing for an extension of the shaft 16. A. larger wheel 18 is dis posed in mesh with the' smaller gear wheels 15 inwardly of the bearing bracket 17, and a" belt pulley 19 is keyed to the w outer end of the shaft 16 for operative ponnec'tion by a suitable endless belt to'convey, power to the machine desired to be operated. The .gear wheel '18 and the pulley 19 are each. provided with automatically oiled bearings, one out which is disposed, upon the inside of the gear wheel. and bolted" to the platform, and the other is secured to the bracket 17 between said gear wheel and pulley to insure strength. its will also be noted, in Fig. 2 of the drawings, the bearing bracket 17 issecured t0 the :franiebelow the larger gear wheel 18 and is offset in order to properly position the some between the Wheel and'pulley 35 for rotatably supporting the shaft 16.

In order to rigidly hold the automobile in position sothat the drive wheels thereof will properly engage the drums, I provide an adjustable brace which is adapted to be so secured tothe drive axle of the vehicleto hold the same in a rigid position. This brace comprises a pair otdivergent arms 20 and 21, whichv have their lower ends connected-t0. a'brace rod 23 disposed par allcl with the horizontal portionulO and secured to the portion 10 centrally of the, widthof the platform. This brace rod 23 is p ovided with a longitudinal. slot 2%, and bolt; 25'carried by the lower ends of the arms 20 and 21 are disposed therethrough for sliding: movement and .are adapted to be held in their adjustedfpositioii by means oflever' nuts 26 threaded thereon, so as to frictionally bind thefiparts together.

As will-be]nioreespecially noted in Fig.

3 of-the drawingathe upper ondot the arm 20 sccured'to the arm 2i by a bolt and nut connection-27' and saidarin i2 is prowhereby 11,6 engagement may he changed to dittcreht positions, to regulate the'hoigh; of the arm providing bifurcated arms 30 having openinsure rotation of the drums ings therethrough. A clamp arm 31 having. a curved upper end 32 is pivotally connected through the medium of a bolt extended through the-openings in the arm'30 and both of said portions 29 and 32 arepro-,, vided with a rubber covering 32 to prevent destruction of the axle or casing thereof, and a clevis 33 is slidably m'ounted upon the arm 21 and adapted to beImoved over the clamp arm 31 to hold the curved portions in binding contact with the. axle, and

.a set screw 9 is disposed through the clevis for holding the same in position.

Theinclined approaches 11 are, of the proper slope to enable the automobile to be driven on to the platform and when the drive wheels are positioned between the two drums, thesupporting arm just described is attached to the axle ofthe vehicle in a proper position to. engage the. said wheels with the drums at the proper pressure to The device may then be .operated and power conveyed through the gears and belt pulley 19 through 'a suitable belt 35 to the machine desired to be driven and when itis desired to cease operation thereof, the clamp is removed from the axle and the drums are held from rotation by means of a brake 36, which comprises a flat strip of metal of sufficient strength and stiffness and. which is bolted to the horizontal portion 10 of the platform and extended aroundthe drum over which the axle clamp is extended and is provided with a horizontally disposed handle portion 37 which is adapted to engage a vertical ratchetbar 38 also secured to the platform, so that the ratchet may be held in binding Contact with the drum to preventmovement 6f the parts of the motor and hold thed-rums in a-stationary positionso. that the automobile may be driven on and off of the platform. It is' also apparent that by slid- .ing the two arms 20 and Ql-upon the brace rod 23, the axle clamp may be adjusted vertically to permit its use inrconnection with (lifl'erentmakes of automobiles, and by mounting the structure upon the platform, the device is rendered portable, so that it may be conveyed from place to place and;

for useuasidesired. The provision of the drums which extend the full width of the platform makes it-mueh easier to properly position the automobile for operation and by covering the same with rubber, a more positive drive is insured.

Having thus described my invention, what I claim is:

' 1. An automobile power motor comprising a platform havinginclined approaches to permit the conveyance of the automobile thereon, friction drums rotatably carried by the platform and .projecting thereabove, rotatable-means operatively connected with the drums for transmitting power, and an adjustable brace adapted for engagement with the drive axle of the automobile to position the drive wheels in engagement with thedrums, said brace comprising a slotted rod carried by the platform, a pair of divergent arms slidably engaged with the slot and adjustably secured together at their upper ends and a clamp carried by one of the arms for engagement with the axle.

2. In a motor for deriving power from the drive wheels of a vehicle; of a pair of drums provided with operative connections fcr transmitting power from their rotation,

said drums being spaced-apart for engagement with said Wheels and means for'holding the latter in such position, said means comprising a pair of divergent arms ad- 'justably secured together at their upper ends, means for securing the lower-ends of the arms for independent slidable move-' "carried by the last mentioned arm to hold the clamp in an engaged position;

3. The combination with a support for a motor vehicle, a power transmitting driving arm having a curved jaw pivotally connected to said curved aw, sa d curved aws adapted for clamping engagement with the rear axle of said vehicle, and means on one of said adjustable arms and said shorter arm for adjusting said arms.
